EMERGENCY-DOOB-LOCK-OPEBATING MECHANISM.

Specification of Letters Patent.

Patented July 5, 1921.

Application filed September 30, 1918. Serial No. 256,234.

T 0 all whom it may concern:

Be it known that I, WILLIAM B. BoLLEs, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented a certain new and useful Improvement inEmergency- Door-Loclr0perating Mechanism, of which the following is afull, clear, and exact description.

This invention relates to a device for use in connection with doors,more particularly exit doors from theaters, halls, and other buildings.v

The purpose of the invention is to provide a means whereby the lock orlocking means for a door may be easily operated by a bar, handle, lever,or similar element which is so placed upon the door as to be readilyaccessible to persons seeking exit.

A further purpose and object is to provide such a mechanism, which issimple in construction, and one in which the parts are so arranged andguided that the parts can not jam, and thereby be non-effective in theprocess of opening the door.

Generally speaking, the invention may be said to comprise the elementsand combinations thereof set forth in the accompanying claims.

Reference should be had to the accompanying drawings forming a part ofthis specification, in which Figure 1 is an elevation showing a doorequipped with locking bolts and operating mechanism for the same; Fig. 2is an elevation of the mechanism by which the bolts are operated; Fig. 3.is a side elevation with portions in sec tion of the construction suchas shown in Fig. 2; Fig. 4 is an elevation showing a modified form ofconstruction; Fig.5 is an elevation showing a modified form ofconstruction; and Fig. 6 is an elevation showing a modified form ofconstruction.

. Referring to the drawings, 1 indicates a door, 2 and 3 indicatelocking bolts for the door which cooperate with suitable detentiondevices carried in the door frame and by the floor adjacent the bottomof the door.

Either formed as part of these latches, or secured thereto, are rods 4and 5. These rods are secured to sliding members 6 and 7, such asindicated in Fig. 2. The sliding members are in part mounted within thecasing 8, this casing having a cover such as indicated at 9 in Fig. 3,which normally occupies the position shown in that figure.

The casing 8 with its contents is secured to the door after the fashionindicated in Fig. 1.

Within the casing I extend the sliding members 6 and 7, as indicated,and cooperatmg with the sliding member 6 is a Wall 10 which preferablyis formed integral with the casing, also a short wall 11, whichcooperates with an opposite side of the sliding member. The member 6also bears against the face of the casing 8 and is engaged by the cover9 when it is facing any position. Thus the member 6 is held againstmovement, and the fit between the various parts which engage the member6 is such as to permit a free movement of the member 6, but neverthelessto prevent any movement in a direction otherwise than substantiallylinear.

The member 7 also engages in part with the wall 10, and preferably thereis a wall 12 which also engages with the member 7 to assist in guidingit in a linear direction. Adjacent the lower end of the casing there isa wall 13, also a short wall 14, which engage with the sides of themember 7 for the purpose of guiding the same.

The member 7 is provided with an exten sion 7 and the member 6 isprovided with a recess or socket portion 6 The recess 6 receives a coilspring 15, and the head 7'" of the member 7 extends within the recess 6.and engages with the end of the coil spring 15, so that when the members6 and 7 move toward each other, the coil spring is placed undercompression, which compression serves to restore the members 6 and 7 totheir normal position when the pressure which holds spring 15compressed, is released.

The members 6 and 7 are adapted to be moved simultaneously so that thelatches for the door at the top and bottom thereof will besimultaneouslymoved, that the door may be opened.

For the purpose of so joining the members 6 and 7 that they may besimultaneously moved, I employ a pivoted lever 16, which lever ispivoted at its central portion, and at each of its ends is provided withan upstanding pin, as indicated at 17 and 18. The member 6 has anextension 6 which is provided witha pin 6. This extension is preferablyprovided with a part 6 which engages with a wall of the casing 8, sothat as the member 6 and the parts 6 and 6? are and 14, to maintain thesame in proper'linear I l arrangement. The extenslon 7 b is providedmoved, the bearing of the portion fi upon the casing will serve to takea part of any 6 and 7 to move in a linear direction 7 Link 19cooperateswith the pins 17 and 6 The member 7 is provided with an exten-,sion 7? which has. a part 7 that "engages with the wall of the casing8. This portion 7 serves when the members 6'and 7 are moved,rtogetherwith. the walls 10, 12,13,

1 with a pin 7?. A link 20 codperatesi with the: pins 7 and 18.

, As .hefoie stated,

7, and forthisfpnrpose, the member 7 is n o rtised 'clear through, asindicated ,ingdotted lines at 7 in Fig. 6. I, Upon'the casing there ispivoted. a lever 21. This lever is provided with a rearwardly extending.portion 21 as indicated in Fig. 3. Above the lever there is a portion ofthe casing indicated at 22, which in part extends over thatportion-ofthe lever 21 at which it is pillqtedwsq s to P v n the hand or o g ofthe Operator from becomin caught behind the lever and preventing theoperation thereof, Q The'extension 21 of the lever 21' may be describedas substantially cylindrical in its shape except at that'fportionfbywhich it is 7 top portionof the said opening. The mecha joined to thelever. 21. of the lever extends into-and occupies an opening 7 i whichis formed in the member '7, the member 21? normally engaging with the V.nismwhich has thus far been described will fby its operationwill causethe members 6 operate when the lever 21 is depressed, and

and 7 to simultaneouslymove into the casing, or toward each other andcompress the springf15 This will at-once be'eviden-t by an examinationof the drawingaior when a the; lever 21 is depressed, vit willcansethe Ispect'to the casing.

' in'turn cause the link 19 to act upon thepin into the casing.Therefora by theoperation" tion and move the members 6 and' 7 slidingmember ,7 to move inwardly with re This movement will causevthe link 20to raise the pin 18, which will in turn depress the pin 17, and thiswill 6?, thereby causing themember "6 to move original and normalposition.

it may happen that the person endeavoringrto operate the lever 21,would, in the excitementof a hasty egress, grasp the lever I 21 andraiseiit instead ofa-pushingit down,

and in order to provide forssnch acontingency and make it'possible' torelease the 4 he lever 16 is pivoted atitscentral portion, as indicatedat 1 6, andthe lever 16 extends beneath the memberv The extension 21locking bolts under such .a situation, I have V provided the followingconstruction; thrust, and assist in enabling the'members The member '7is provided with a recess the pin 17, and atits 'lowerend has anextension 23 which extends into the recess 7 and normally lies justbeneath the portion 7 mortised out. A link 23, coeperates with I V c H21ofthe lever. -21, .This link 23 is preferably provided with 'aroller24, adjacent its lower end, which engages'with the sidewall of thecasing 78 in order to vprovide "a; rolling contact between the roller 24and -;the wall of theg casing 8, and further to provide a backing forthe. lower end of, the "link 23.:

The Y recess 7 is sufficiently extended so that the projection 23 maymove through the recess for a snfiicien't distance to accommodate anymovement required for the operation of the members of the mechanism.

7 "The link123 maybe formed"integralwith.

the link l9, so that'thelinks 19 and 123' are" in eifect a singleoperating member, in which event the openingindicated v at. 19? isslightly elliptical inshape. to accommodatefithe slightlycircular.movement of the pin 17 as the lever 1 6;tiltsabout its pivot.

*With the members of the mechanism 'ar f ranged as just described, ;ifthe operating lever 21 be raised, the part 21 of the lever is odepressed, which moves the projection 123 downwardly throughjthe recess75, int-urn carrying the link 23 idow-nward-ly which I' V communicatesits motion to theiink 19 and so through to the member :6, .ca-usingsthesame tocbe movedin a directioninto the casing. The downward movement oflink 23' 7, causes 'thelevergltl to tilt, thereby drawing c v in anupward 'directionthe link 20,}which' j in turn cansesthemember7 to-moveinto'the;

casing;

Thus it willbe'seenthat the slidingmem bers 6 and 7 areoperated inamanner to withdraw the locking bolts :whether; the lever 21 bedepressedor raised. r In Fig.7 6 I have shown a construction in whichthe members 16 and7 are theiqsame as that described, and in fact, mostof the parts are exactly the sameythe only -difierence being thatthe-link 19 and the link 23am formed as independent members. V In Fig.4:1 haveshown a slightly modified form relating to themanneroiconnection ofthe lever '16 with the sliding member 7. I Inthisconstructionthe lever 16 has apin 16*; which cooperates withan-extension formedon the member 7. .This extension is opening, in theportion 7 being slightly elliptical in form so as to accommodate the areformed separately, and; are caused each to engage withthepin'17of thelever 16.

. V InF-ig. 5 therparts are thesame. as :that

lformed adjacent, theportion of thermember, 7 which cooperateswith;.;the lever '16, the

shown in Fig. 4, with the exception that the links 19 and 23 are madeintegral, and at that portion which cooperates with the lever 16 thereis an opening 17 which is slightly elliptical in form in order toaccommodate the pin 17 in its slightly circular movement.
